Hyper-V's NIC SR-IOV implementation needs a Hyper-V synthetic NIC and a VF NIC to work together (both NICs have the same MAC address), mainly to support seamless live migration. When the VF device becomes UP (or DOWN), the synthetic NIC driver needs to switch the data path from the synthetic NIC to the VF (or the opposite). Note: multicast/broadcast packets are still received through the synthetic NIC and we need to inject the packets through the VF interface (if the VF is UP), even if the synthetic NIC is DOWN (so we need to force the rxfilter to be NDIS_PACKET_TYPE_PROMISCUOUS, when the VF is UP).
